Sonchus asper is an annual plant (native to Europe) that may reach as much as 180cm in height with spiny leaves and yellow flowers resembling those of the dandelion. The leaves are bluish-green, simple, lanceolate, with wavy and sometimes lobed margins, covered in spines on both the margins and beneath. The base of the leaf surrounds the stem. The leaves and stems emit a milky sap when cut. The flowers grow in clusters and the end of the stems. | Sonchus asper is an annual plant (native to Europe) that may reach as much as 180cm in height with spiny leaves and yellow flowers resembling those of the dandelion.
